To (LZZ wiz/om it may concern.-

Be it known that I, LAURIS L. CARSON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and -useful Improvements in Printing-Presses, of which improvements the following is a specification. l

It is the custom withmany newspaper publishersto allow news companies and other dealers a rebate for unsold copies. In making returns to the publishing companies the dealers tear oif the head-lines of the first page of the paper and send them to the publishers. The latter are subjected to great frauds by newsboys and others tearing off the head-lines from papers which have been thrown away in street-cars and elsewhere. These fraudulent head-lines of papers are sent to the publishers as portions of unsold papers, thereby subjecting them to great loss. Many devices have been suggested for preventing these fraudulent practices, such as fastening together two or more pages of the paperin such manner by paste or mechanical devices that the portions which are to be returned to the publishers will be mutilated when the paper is opened by the reader. The means heretofore suggested have been im practicable either for the reason-that the pages cannot be secured together as rapidly as the paper is printed and folded or the pages have been so secured together that portions of the readingmatter is mutilated.

The object of the present invention is to provide means operative at the same speed as the printing and folding mechanism to partially isolate or sever a `portion of a page of paper and to cause suchpartially isolated or severed portion to adhere to an adjoining page, so that on the separation of the pages the partially-severed portions will be easily separated from its page along the line of partial separation and remain adherent to the other page. In the accompanying drawings, forming a part of this specification, Figure l is a View in side elevation of a portion of a printingpress having my improvements applied thereto. Fig. 2 is a top plan view of the same. Fig. 3 isa side elevation, on an enlarged scale,

of the perforating and paste-applying mechanism. Fig. 4 is a sectional view of the same, the plane of section being indicated by the line 1V lV, Fig. 3. Fig. 5 is an enlarged view of portions of the perforating-rolls'. Fig. 6 is a perspective view showing my improvements applied to a press of` a different c-onstruction. Fig. 7 is a sectional elevation. Fig. 8 is a side elevation, on an enlarged scale, of the modiiied construction of the perforating and paste-applying mechanisms. Fig. 9 is' a plan View of the same, a portion of one of the perforating-disks and its driving-pinion and bearing being broken away; and Fig. 10 shows a paper perforated and pasted.

In the practice of my invention the edge of one of the webs, preferably the outside web a, is caused to pass on its way from the printing-cylinders to the folders between rollsll and lf. One of these rolls is provided with a series of pins 2 and the other roll with holes 3, into which the pins may pass, so as to form a line or lines of perforations in the web. These pins and holes may be arranged, as shown, to -form a line of perforations diagonally across the upper right-hand corner of a sheet when severed from the web, as shown in Fig. 10,.or may be arranged so as to partially sever portions of any desired shape along any edge of the web. After the formation of the perforationspaste is applied to the inner surface of the partially-severedV sections or to the outer side of the second or inner web by rolls i and 5 in such position that when the two webs pass one onto the other just prior to. the operation of the folders the partially-severed sections will be caused to tightly adhere to the adjacent web.

It will be readily understood by those skilled in the art that the perforating and paste-applying mechanisms can be arranged so as to sever or isolate any portion of any of the sheets forming the paper and to so apply the paste that such partially severed or isolated portion will firmly adhere to the adjacent sheet, so that such partially-severed portion will be 'entirely torn out when the paper is opened out. As a general thing it will be more convenient to arrange the perforating and pasting rollers so as to operate on the .outer edges of the outside webs, as shown in IOO Figs. 1, 2, 6, and 7 A desirable construction in so using the mechanism consists in securing'the rolls 1 and l on the extended hubs 6 of pinions 7 and 8, which intermesh and are mounted on pins 9 and 10, secured in the frame l1. This frame is so fastened to the frame of the printing-press that the edge of the outside web will pass between the rolls 1i and l, and the rolls are driven by a train of gearing extending from any suitable part of the press and so proportioned that the rolls 1 and l will have a peripheral speed equal to the speed of the webs through the press.

It is preferred to apply the paste tothe inner side of the portion partially isolated; butin some presses the arrangement ot' the guiderollers and the proximity of the first and second websand other structural features of the press may render such application of the paste impraeticable-as, for example, in the form of press shown in Figs. 1 and 2 the outside Web a after being operated on-by the rolls 1 and 1u passes over the guide-roller 12 and then joins the inner web b, and the two Websare carried along by tapes 13 tothe guide-roller 14, whence the webs pass to the folder. -If the paste should be applied te the inner surface of any portion of the web a, it would be rubbed off on the guide-roller 12 and then smeared on other parts of the web. To avoid such an objectionable feature, provision is made for applying the paste to portions of the outer surface of the inner web b correspond-I ing in position to the partially severed or isolated portions of the web a, so that when the webs come together such partially-severed portions of web awill be pressed onto the pasted portion of web b. 1t is also characteristic of the arrangement of the outer andj inner webs in some presses that the webs are too nearly adjacent to permit of the employ-'- ment of a paste-applying roll equal in peripheral length to the length of the sheets into which the webs are divided. In such case ag smaller roll having a peripheral length equal:

to half or quarter of the length of the sheetslI is so mounted on a movable part, which is; shifted to bring the paste-applyin g portion of? the roll against the web b at every second, third, or fourth revolution thereof, dependentf upon the relation of the length of the periph-g ery of 'the roll to the length of sheets intoi which the web is to be divided. In applying@ my improvement to such a press the roll 4 ist preferably secured on the extended hub of# Ithe pinion 15, which is loosely mounted on a pin 16, which is secured on one arm of a le-;

ver 17. This lever is, pivot-ally mounted onl the pin 10, supporting the rol l1, and the op posite end of the lever projects into the path of lmovement of a cam projection 7 on the hub of the pinion 7. As the rolls 1 and 1 have a peripheral length equal'to the lengths: ofthe sheets, they are geared to make one revolution while any given point of the con- `tinuous web is traveling a distance equal to the length of sheets in to which the web is? subsequently cut. vThe pin 16, on which the pinion 15 and roll 4 are mounted, is so located on the arm of the lever 17 that the pinion will'be lconstantly in mesh with the pinion 7, therebyinsuring the constant rotation of the roll 4. This roll is preferably provided with a projection 18, having a shape and superficial area proportional to the area to which paste is to be applied. As shown in Fig. 1, the lever 17 is so shaped that the roll 4 will project between the webs a and b, and the roll is so held normally by the spring 1S) that the projection 18 will press against the outer surface of the web b at each revolution; but contact with the web is prevented at every other revolution of the roll by the shifting of the lever 17 by the cam 7. In order that the projection 18 may press firmly against the web b, the latter is supported bya roll 5, loosely mounted on a pin 20, projecting from an angular extension 2l of the frame l1; This roll is so arranged that the web b will always pass along in contact therewith and will rotate freely when the web is being acted on by the projection 18..

Paste is applied to the surface of the projection by'a roll 22, mounted in the lower end of a paste-receptacle 23, carried by the lever 17.. The roll is rotated intermittingly by a pin 24 on the side, the roll 4 striking against and shifting a lever 25, mounted on the shaft of the roll 22. On the lever is mounted a spring-actuated pawl 26, adapted to engage the ratchet 27 on the shaft of roll 22. As the roll 22 is rotated it will bring portions newly covered with paste in position to apply the paste to the surface of the projection 18.

In some presses the arrangement of the webs is such as to afford ample room for the application of my improvements thereto in such manner that portions of the outside web can not only be perforated or partially severed, but the paste can be applied to the .inner'surface of such portions. Such a press is illustrated in Figs. 6 and 7, the outsideweb being indicated at a and the inside web at I, said webs being superposed one upon the other as they pass around the guide-roller 28. In adapting my improvements to such a machine the rolls 4 and 5 are so arranged that the web a will pass between immediately after being operated on by the-rolls 1 and 1. The roll IOO 4 is made of such a size that the diameter of jection 18 is equal to the diameter of the roll lgorl, and the pin on which the roll and its driving-pinion are mounted is xed to the frame 11. The paste-'receptacle 23 is connected to the frame 11 in suoli manner that its roll 22 is held in operative relation to the roll 4.

As the copies of some editions are not rcturnable and need not, therefore, be marked, it is preferred that provision should'be made for shifting the lmarking mechanism ont of the line of movement of the webs. To this end the frame 11 is provided with sockets 29 for the reception of supporting-pins 30, se-

cured to the frame of the press. A lever 3l is Aconnected by a link 32 to the frame 11, whereby the frame can be shifted along the pins 30 into and out of operative position, as required. l
